bytes feature of aead is not re-exported by AEADs

[davepollack]

Hi,

I have a BytesMut given to me by quinn-proto, that I would like to use as a Buffer with chacha20poly1305. The impl of Buffer for BytesMut is gated behind the bytes feature.

However I cannot specify features = ["bytes"] with chacha20poly1305, as its Cargo.toml (and I think other AEADs) does not re-export the feature. This seems to be inconsistent with other similar features like heapless and arrayvec that are re-exported.

Currently I've added aead with features = ["bytes"] to my Cargo.toml to union in the feature, which isn't too bad, but I'm wondering if this is an oversight.

Cheers

Yeah, we can potentially add passthroughs for this like we have for heapless
